The cleaned debris is lifted and dehydrated along the inclined conveyor belt, and finally automatically discharged from the discharge port, realizing the integrated operation of cleaning and conveying, which will not be described here.

[0029] The screening assembly includes three discharge ports opened on the processing box 2.

[0031] The dust collection end of the dust collection device 21 is connected to the air supply pipe 10. The dust collection device 21 is a prior art and is mainly composed of a filtering system, a dust collecting bin, a fan and a motor. Its working principle is that the motor drives the fan to rotate at a high speed to form a negative pressure airflow inside the device, and the dust-laden air is sucked in through the dust suction port. When the airflow passes through the multi-stage filtration system, the dust is intercepted by the filter material and falls into the dust collecting bin, and the purified air is finally discharged. I will not go into details here. The lower end surfaces of the two vibrating plates 4 are fixedly connected to the top rod 30, and the lower end surfaces of the two top rods 30 are fixedly connected to the impact balls. The impact balls can vibrate with the vibrating plates 4, and the impact balls can continuously impact the inner wall of the processing box 2 to facilitate the discharge of the screened plastic debris. A protective pad layer is provided on the two elliptical plates 34.

[0033] The detailed working process of the present invention is as follows:

At the same time, it reduces the dust adhesion on the plastic debris, improves the purity of plastic particles in the subsequent cleaning link, and ensures stable product quality. The plastic debris then enters the cleaning box 1 for cleaning. After the cleaning is completed, the water in the cleaning box 1 is discharged, and then the cylinder 22 drives the baffle 23 to rise. Under the transmission of the rack 25 and the rotating gear 24, the threaded rod 28 rotates, causing the scraper 27 to move, scraping the sediment at the bottom of the cleaning box 1 to the discharge outlet for discharge, making it easy to clean the cleaning box 1, reducing the workload of the staff, and improving the portability and practicality of the device.
